Why Ignition Cylinders Stick, Bind, or Refuse to Turn
The ignition cylinder is a small but complex lock mechanism that interacts with your key's cut pattern dozens of times a day. Over thousands of cycles, the internal wafers or pins wear unevenly, the springs weaken, and the cylinder barrel develops play it shouldn't have. In New York's climate — where cars sit through humid summers and brutal winters — lubricants dry out or congeal, causing the cylinder to bind without any warning. Road salt, which gets tracked into vehicles throughout the boroughs from November through March, can migrate into the ignition and accelerate corrosion on the internal components.
A bent or worn key is another major culprit. Because New York drivers often carry dense key rings — building fobs, bike locks, office keys — the added weight puts constant lateral stress on the ignition cylinder, gradually deforming it. Using a worn key on an already-tired cylinder creates a feedback loop: the key cuts don't align cleanly with the wafers, the driver forces the turn, and internal components crack or shift out of position. Attempting to force a stuck ignition almost always makes the underlying problem worse, and in some cases snaps the key inside the cylinder — a separate but equally urgent repair.
